Processing and Solutions

Stations of UNAVCO network used for PPP-AR server processing.

Coordinate Estimate
Real-time PPP-AR client coordinate solution for UNAVCO P121. The last real-time test processing was performed on April 12, 2013. Correction data from regional PPP-AR server can be used at client stations up to 1,000 km from the centroid of server network if enough number of common satellites with server network are observed in client stations. Real-time server input file is RT_NET_SRV-PPPAR_GX_MWL3_REGIONAL.

Sample data and Setting

Item/Parameters Notes and Setting

(Please use the template file by replacing the stations).
Real-time Processing Start time: MJD 56394.057 (2013/04/11)
Used data GPS phase L1/L2, code P1/P2
Get data UNAVCO data is open to registerd users (please see Data in UNAVCO website.
Satellite products IGU orbit (predcited part) stored (synced with IGS server) in local server is used for real-time processing.
Setting in processing P395 is fixed, and coordinate of P367 is estimated with 1Hz.
Constrain A priori coordinate 100m, Coordinate change 100m/s, ZTD for P367 1e-5 m/s
Processing cost N/A
SSR Input Port 8111 (Refer setting in server input file to get server correction)
Validation Repeatability of coordinate solutions (reference is a priori coordinate).
